My 810 is less than a year and a half old, and I've already had to replace the battery. Probably you need to do the same.

There are cheap ones available from third party vendors, but they are often defective or of lower capacity. I recommend paying for a Nokia battery.

(The Stupid Little Genius issue seems to be developing over this thread).

BTW, is a 2.5 day battery life with PDA-like usage* common (should read: good enough)?

I'm trying to learn gnuplot; already made some nice battery charge plots with data read from HAL. I'm impressed how the NIT manages to keep energy consumption to a minimum while idle (voltage stays flat for a whole night!), but I think charge drops way too much as soon as I start fiddling with it.

*(PDA-like = usually 5-10 minutes every hour, wifi always on)

In case you didn't figure it out, the values reported aren't updated when device is idle, that's why your graph is flat.

kcbatt can get the raw battery voltage from retu, you can see it sloping when idle too..

The battery on mine started to suck lately with wifi, too.

I generally keep open on it all day an IM window, Skype, and Mauku ( Twitter program). Could any of those be causing the problem? I also recently added a "countdown".

If Mauku can't connect or has some oddity it will drain the battery. Rare but it happens.

I know you're using SKYPE but I have had Gizmo kill the battery in short order. Remember anything that polls the network will drain the battery some.

I don't know which IM program you're using but I've found that the built in has less of an impact on the battery than pidgin.

Lastly, I don't know if you are using the built in mail client but if so, if it screws up, your battery is toast.

I'm running an 800 with a 2+ year old battery and I can still go all day so long as I don't hit a flash website or have the mail app go nuts.

After about a year, I had to replace my n810 battery. Bought a mugen one, because they are cheaper and higher capacity than a OEM battery.

I've always had pretty good battery life myself on a tablet about two years old. Light usage gets me a week or so, moderate about 4 days and heavy, maybe two days. Of course it all depends on you definitions of light, moderate and heavy. (1hr, 2hr, 4hr a day for me).

I get 10min of heavy use. I am thinking about getting the mungen battery. Heavy use in my opinion is googl tlk and using the browser. Any type of voip program on my n810 will kill the battery in no time flat. I would like to know is there something OS or APP related killing the battery or is it just a short life battery. I have had the oem battery that comes with the n810 since its realease or about two years. I have never had a cell phone battery do this so why are the batteries in the n810 acting this way.

Buy a cheap $10 battery as a spare. Then you can quickly determine if you have a battery problem.

I would like to run a battery test using battery-status. Is there any way to keep the display from going to sleep so I can run a test of continuous use?

If it always acted this way, there may be something wrong with the unit.

If it has just started acting this way after two years, it sounds like the battery needs replacing.
